Consider the following for the next five (05) items that follow: The frequency distribution of 205 observations on X is given below: X: 3, 5, 6, 7; Frequency: f, f+2, f−3, f+6. What is the most appropriate graphical representation of the given frequency distribution of X?
Elementary MathematicsStatistics
- ABar diagram
- BHistogram
- CFrequency polygon
- DPie Chart
Explanation
X takes the isolated values 3, 5, 6, 7, so the data are discrete, for which the bar diagram is the standard representation (a histogram suits continuous class intervals). Hence option (a). Note: this key is disputed — verify against the official UPSC key.
